Essentially, you design the cabinetry layout you want using IKEA's software then you send your plans to SemiHandmade and they use the scheme to create a custom kitchen, closet, bathroom etc. for you. The cabinets take about 7-8 weeks once a deposit is received and ship UPS ground.
SemiHandmade's doors are veneer and they offer roughly 21 material choices organized into 4 different price categories. The website indicates that most of their customers spend between $5,000 to $10,000 on their custom doors. Add this to a typical cost of IKEA boxes and hardware - $1,000 to $3,000 - and installation - $1500 to $2500 - and the all in range is $8,000 - $15,000. While this is still a lot of money, its about 30-40% off a typical custom project. Below are some examples of their completed projects - I think they look so good and totally custom!
